ABSTRACT
OBJECTIVE@#To observe the clinical effect of acupuncture at sphenopalatine ganglion combined with conventional acupuncture for episodic cluster headache (CH).@*METHODS@#One hundred and eighty patients with episodic CH were randomly divided into a combined group (60 cases, 3 cases dropped off)，an acupuncture group (60 cases, 2 cases dropped off) and a sphenopalatine ganglion group (60 cases, 2 cases dropped off and 1 case was removed). The patients in the acupuncture group were treated with conventional acupuncture at Touwei (ST 8), Yintang (GV 24+), Yangbai (GB 14), Hegu (LI 4), etc., once a day, 6 times a week. The patients in the sphenopalatine ganglion group were treated with acupuncture at sphenopalatine ganglion, once every other day, 3 times a week. On the basis of the conventional acupuncture, the combined group was treated with acupuncture at sphenopalatine ganglion once every other day. Two weeks were taken as a course of treatment, and 3 courses of treatment were required in the 3 groups. The score of visual analogue scale (VAS), the number of headache attacks per week, the duration of each headache attack and the score of migraine-specific quality of life questionnaire version 2.1 (MSQ) were observed before and after treatment and in follow-up of 3 months after treatment. The clinical efficacy of each group was compared.@*RESULTS@#After treatment and in follow-up, the VAS score of headache, the number of headache attacks per week, the duration of each headache attack, and each various scores and the total score of MSQ of each group were lower than those before treatment (P<0.01). Except that the number of headache attacks per week in the combined group was lower than the sphenopalatine ganglion group (P<0.01), other indexes in the combined group were lower than the other two groups (P<0.05, P<0.01). The total effective rate in the combined group was 93.0% (53/57), which was higher than 75.9% (44/58) in the acupuncture group and 73.7% (42/57) in the sphenopalatine ganglion group（P<0.05, P<0.01).@*CONCLUSION@#Acupuncture at sphenopalatine ganglion combined with conventional acupuncture could reduce the degree of pain in patients with episodic CH, reduce the number and duration of headache attacks, and improve the quality of life of patients. It is more effective than simple conventional acupuncture or acupuncture at sphenopalatine ganglion alone.

BACKGROUND AND PURPOSE: Cluster headache (CH) is frequently either not diagnosed or the diagnosis is delayed. We addressed this issue by developing the self-administered Cluster Headache Screening Questionnaire (CHSQ). METHODS: Experts selected items from the diagnostic criteria of CH and the characteristics of migraine. The questionnaire was administered to first-visit headache patients at nine headache clinics. The finally developed CHSQ included items based on the differences in responses between CH and non-CH patients, and the accuracy and reliability of the scoring model were assessed. RESULTS: Forty-two patients with CH, 207 migraineurs, 73 with tension-type headache, and 18 with primary stabbing headache were enrolled. The CHSQ item were scored as follows: 3 points for ipsilateral eye symptoms, agitation, and duration; 2 points for clustering patterns; and 1 point for the male sex, unilateral pain, disability, ipsilateral nasal symptoms, and frequency. The total score of the CHSQ ranged from 0 to 16. The mean score was higher in patients with CH than in non-CH patients (12.9 vs. 3.4, p 8 points, the CHSQ had a sensitivity, specificity, positive predictive value, and negative predictive value of 95.2%, 96%, 76.9%, and 99.3%, respectively. CONCLUSIONS: The CHSQ is a reliable screening tool for the rapid identification of CH.

BACKGROUND AND PURPOSE: Cluster headache (CH) can present with migrainous symptoms such as nausea, photophobia, and phonophobia. In addition, an overlap between CH and migraine has been reported. This study aimed to determine the differences in the characteristics of CH according to the presence of comorbid migraine. METHODS: This study was performed using data from a prospective multicenter registry study of CH involving 16 headache clinics. CH and migraine were diagnosed by headache specialists at each hospital based on third edition of the International Classification of Headache Disorders (ICHD-3). We interviewed patients with comorbid migraine to obtain detailed information about migraine. The characteristics and psychological comorbidities of CH were compared between patients with and without comorbid migraine. RESULTS: Thirty (15.6%) of 192 patients with CH had comorbid migraine, comprising 18 with migraine without aura, 1 with migraine with aura, 3 with chronic migraine, and 8 with probable migraine. Compared to patients with CH without migraine, patients with CH with comorbid migraine had a shorter duration of CH after the first episode [5.4±7.4 vs. 9.0±8.2 years (mean±standard deviation), p=0.008], a lower frequency of episodic CH (50.0% vs. 73.5%, p=0.010), and a higher frequency of chronic CH (13.3% vs. 3.7%, p=0.033). Psychiatric comorbidities did not differ between patients with and without comorbid migraine. The headaches experienced by patients could be distinguished based on their trigeminal autonomic symptoms, pulsating character, severity, and pain location. CONCLUSIONS: Distinct characteristics of CH remained unchanged in patients with comorbid migraine with the exception of an increased frequency of chronic CH. The most appropriate management of CH requires clinicians to check the history of preceding migraine, particularly in cases of chronic CH.

OBJECTIVE: We aimed to develop the clinical guideline for headache by the systematic review and synthesis of existing evidence-based guidelines. The purpose of developing the guideline was to improve the appropriateness of diagnosis and treatment of headache disorder, and consequently, to improve patients’ pain control and quality of life. The guideline broadly covers the differential diagnosis and treatment of tension-type headache, migraine, cluster headache, and medication-overuse headache. METHODS: This is a methodological study based on the ADAPTE methodology, including a systematic review of the literature, quality assessment of the guidelines using the Appraisal of Clinical Guidelines for REsearch & Evaluation II (AGREE II) Instrument, as well as an external review using a Delphi technique. The inclusion criteria for systematic search were as follows: topic-relevant, up-to-date guidelines including evidence from within 5 years, evidence-based guidelines, guidelines written in English or Korean, and guidelines issued by academic institutions or government agencies. RESULTS: We selected five guidelines and conducted their quality assessment using the AGREE II Instrument. As a result, one guideline was found to be eligible for adaptation. For 13 key questions, a total of 39 recommendations were proposed with the grading system and revised using the nominal group technique. CONCLUSION: Recommendations should be applied to actual clinical sites to achieve the ultimate goal of this guideline; therefore, follow-up activities, such as monitoring of guideline usage and assessment of applicability of the recommendations, should be performed in the future. Further assessment of the effectiveness of the guideline in Korea is needed.

ABSTRACT Objective To describe the evolution of 15 patients who were treated for difficult-to-control episodic and chronic cluster headaches with clomiphene. Methods Clomiphene treatment was used for seven chronic and eight episodic cluster headache patients. The chronic patients were refractory to the medication being used, and the episodic patients, in addition to being resistant to conventional medication, had longer cluster headache periods, exceeding the average time of previous cluster cycles. Our main analysis was of the time to pain-free, complete remission, and the length of pain-free time and complete remission. Results Clomiphene was used for 45-180 days. The average time to being pain-free was 15 days and cluster remission was up to 60 days. The average time between being pain-free until cluster remission was 26 days. Conclusions Clomiphene treatment was significantly efficient. It interrupted chronicity in all patients, suggesting the capability of changing the pattern of attacks. It proved to be safe and well tolerated.
RESUMO Objetivo Descrever a evolução de 15 casos de cefaleia em salvas de difícil controle, episódicos e crônicos, tratados com clomifeno. Métodos Foram tratados 7 casos crônicos e 8 episódicos. Os crônicos, refratários aos medicamentos preventivos em uso e os episódicos, além de refratários, apresentaram salva mais longa que as anteriores. Foram analisados o tempo para a ausência das crises, fim da salva e o tempo entre os dois parâmetros. Resultados O clomifeno foi usado por 45 a 180 dias. A média de tempo para a remissão das crises foi de 15 dias e da salva foi de 60 dias. A média entre o fim das crises e da salva foi de 26 dias. Conclusão O clomifeno foi eficaz em ambos os padrões. Foi capaz de interromper a cronicidade em todos os casos, o que sugere uma ação neuromodulatória capaz de mudar o padrão das crises. Mostrou-se seguro e bem tolerado.

Cluster headache (CH) is a rare underdiagnosed primary headache disorder with very severe unilateral pain and autonomic symptoms. Clinical characteristics of Korean patients with CH have not yet been reported. We analyzed the clinical features of CH patients from 11 university hospitals in Korea. Among a total of 200 patients with CH, only 1 patient had chronic CH. The average age of CH patients was 38.1 ± 8.9 years (range 19–60 years) and the average age of onset was 30.7 ± 10.3 years (range 10–57 years). The male-to-female ratio was 7:1 (2.9:1 among teen-onset and 11.7:1 among twenties-onset). Pain was very severe at 9.3 ± 1.0 on the visual analogue scale. The average duration of each attack was 100.6 ± 55.6 minutes and a bout of CH lasted 6.5 ± 4.5 weeks. Autonomic symptoms were present in 93.5% and restlessness or agitation was present in 43.5% of patients. Patients suffered 3.0 ± 3.5 (range 1–25) bouts over 7.3 ± 6.7 (range 1–30) years. Diurnal periodicity and season propensity were present in 68.5% and 44.0% of patients, respectively. There were no sex differences in associated symptoms or diurnal and seasonal periodicity. Korean CH patients had a high male-to-female ratio, relatively short bout duration, and low proportion of chronic CH, unlike CH patients in Western countries.

No presente trabalho teve-se como objetivo avaliar a frequência de exames de tomografia computadorizada craniana (TCC) em pacientes portadores de cefaleia. O estudo baseou-se na aplicação do questionário Migrânea-ID em 166 portadores de cefaleia que procuraram um serviço de imagem para realização de TCC com o intuito de estabelecer o diagnóstico diferencial entre a migrânea e outras afecções neurológicas. 102 (61,45%) pacientes tinham diagnóstico positivo para migrânea e realizaram TCCs sendo que 145 (87,3%) do total da amostra não tiveram alteração nesse exame de imagem. Os indivíduos do estudo apresentaram um elevado índice de normalidade nas TCCs, justificando o fato de na maioria das vezes serem solicitadas desnecessariamente.

La Cefalea en Racimos es una de las cefaleas primarias más dolorosas, con una prevalencia de alrededor de 1-4/1000 adultos de la población general. Aproximadamente el 90% de los individuos afectados experimenta ataques diarios por varias semanas o meses (periodos de racimos o dolor) separados por intervalos libres de dolor que se prolongan por meses o años (periodos de remisión). El restante 10% de los pacientes sufre un patrón más crónico marcado por ataques que persisten por más de 1 año sin periodos de remisión o con periodos de remisión muy cortos. Durante los ataques la mayoría de los pacientes experimenta dolor severo, unilateral,principalmente alrededor de la órbita. El inicio del ataque es rápido y alcanza su pico de intensidad en unos 5 a 15 minutos. La duración usual de los ataques es de 45 minutos hasta 90 minutos, sin embargo pueden prolongarse hasta por 3 o más horas. Se asocian síntomas autonómicos en el mismo lado afectado por el dolor e incluyen inyección conjuntival, epifora, congestión nasal o rinorrea, y Síndrome de Horner de manera parcial. A pesar de que el mecanismo fisiopatológico no se ha dilucidado por completo, su periodicidad circadiana y circanual sugieren la implicación del hipotálamo en la patogénesis de esta afección. La mayoría de los pacientes son manejados de manera exitosa con la terapia médica, la cual puede ser dividida en tratamiento abortivo (como oxígeno o sumatriptan subcutáneo) para ser utilizado durante los ataques y tratamiento profiláctico, el cual busca inducir y mantener los periodos de remisión.
Cluster headache is one of the most painful primary headache disorders with a prevalence of about 1-4/1000 of the adult population. Approximately 90% of affected individuals experience daily attacks for several weeks to months (cluster periods) separated by attack-free intervals lasting for months to years (remission periods). The other 10% of sufferers exhibit a more chronic pattern marked by attacks that persist for longer than 1 year with no remission or only short periods of remission. During attacks, most patients experience severe, unilateral pain, primarily around the orbit. The onset of attack is rapid and reaches peak intensity within 5 to 15 minutes. Attacks typically last from 45 minutes to 90minutes, but they may last longer than 3 or more hours. Associated autonomic symptoms occur on the same side of the headache and include conjunctival injection and lacrimation, nasal congestion or rhinorrhea, and partial Horner syndrome. Despite the pathophysiologic mechanisms remain undetermined, its circadian and circannual periodicity suggest the implication of the hypothalamus in the pathogenesis of the disorder. Most patients are successfully managed with medical therapy; medication management can be divided into abortive treatments (such as oxygen or subcutaneous sumatriptan) for an ongoing attack and prophylactic treatment, which aims to induce and maintain a remission.

Headache disorders, one of most common disease in general population, have been developed according to many versions of international classifications. The primary headaches are those in which no consistently identified organic cause can be determined. It is divided into the following categories: (1) migraine, (2) tension-type headache, (3) cluster headache and other trigeminal autonomic cephalalgias, (4) other primary headaches. This review described a diagnosis of primary headache disorders based on International Classification of Headache Disorders (ICHD)-3 beta criteria.

Cluster headache is a unique primary headache disorder characterized by unilateral severe orbital pain with ipsilateral autonomic symptoms. Symptomatic cluster headache can be caused by variable diseases, such as cerebral aneurysm, arteriovenous malformation, cerebral venous thrombosis, carotid dissection, pituitary tumor, and meningioma. We report a 33-year-old woman with parasellar meningioma mimicking cluster headache. After Novalis stereotactic radiosurgery, pain attacks disappeared.

Introdução: a cefaleia em salvas (CS) é um subtipo de cefaleia primária caracterizado por crises de dor entre 15 e 180 minutos diárias por semanas a meses, geralmente intercalados por períodos de remissão. As crises álgicas são muito intensas, de localização orbital ou periorbital, associadas à sintomatologia de disfunção autonômica. Apesar de sua singular apresentação clínica, a CS permanece afecção pouco reconhecida e subdiagnosticada. Objetivos: descrever e discutir os desafios diagnósticos e terapêuticos da CS a partir de casos clínicos. Material e método: trata-se de uma série de cinco casos de CS em acompanhamento clínico. Resultados: dos 467 pacientes assistidos em ambulatório neurológico, cinco possuíam diagnóstico de CS, correspondendo a 1,07% do total. A apresentação clínica variou pouco em relação à descrição da literatura, com predomínio em homens e da forma episódica, além de haver grande latência entre seu surgimento e o diagnóstico. Conclusão: mesmo em centro terciário de atendimento neurológico, o número de pacientes diagnosticados é pequeno, colaborando para o desconhecimento a respeito da CS, o que contribui para o seu atraso diagnóstico e tratamento específico.
Introduction: cluster headaches (CS) are a subtype of primary headache disorder characterized by daily pain attacks of 15-180 minutes for weeks to months, usually interspersed with periods of remission. Painful crises are very intense, of periorbital or orbital location, associated with symptoms of autonomic dysfunction. Despite its unique clinical presentation, CS remains under-recognized and underdiagnosed. Objectives: To describe and discuss the diagnostic and therapeutic challenges of CS based on clinical cases. Methods: this is a series of fivecases of CS under clinical monitoring. Results: Of the 467 patients treated at the neurological clinic five had a diagnosis of CS, corresponding to 1.07% of the total. The clinical presentation varied little in relation to the description in the literature; it affected predominantly men, episodically. Time elapsed between onset and diagnosis was usually long. Conclusion: Even in a tertiary care neurological center, the number of diagnosed patients is small, which reflects on ignorance about CS and contributes to late diagnosis and lack of specific treatment.

BACKGROUND: The International Classification of Headache Disorders, an essential tool in the diagnosis of headache disorders, has been revised as its 3rd edition, beta (ICHD-IIIbeta). The clinical application in practice is needed to test the feasibility and usefulness of the Korean version of ICHD-IIIbeta. METHODS: Neurologists enrolled consecutive first-visit headache patients from February to March 2014. The classification of headache disorder was done by each investigator according to ICHD-IIIbeta based on the initial structured questionnaire, clinical evaluation, and neuroimaging studies, if needed. A consensus meeting dealt with the cases that were difficult to diagnose. The feasibility and usefulness of this version was assessed by the proportion of unclassified headache disorders using ICHD-IIIbeta compared to the previous version. RESULTS: A total of 207 patients were enrolled: the mean age was 41 years (16-87 years) and women constituted 63.3%. Primary headache disorders were diagnosed in 167 patients (80.7%): 82 migraines, 37 tension-type headaches, 3 cluster headaches, and 45 other primary headache disorders. Thirty-five patients (16.9%) had secondary headache disorders or painful cranial neuropathies/other facial pain and 5 patients (2.4%) could not be classified by ICHD-IIIbeta. The diagnoses differed as compared to the previous version in 32 patients (15.5%): 14.5% differed due to the mitigation of the previous strict criteria and 1% differed due to the introduction of a new diagnostic category. CONCLUSIONS: Classifications by ICHD-IIIbeta are possible in more than 97% of the first-visit headache patients and ICHD-IIIbeta has proved to be more useful than its previous version.

Several studies suggest a strong familial aggregation for cluster headache (CH), but so far none of them have included subjects with probable cluster headache (PCH) in accordance with the International Classification of Headache Disorders. Objective To identify cases of probable cluster headache and to assess the familial aggregation of cluster headache by including these subjects. Method Thirty-six patients attending a headache consultation and diagnosed with trigeminal autonomic headaches were subjected to a questionnaire-based interview. A telephone interview was also applied to all the relatives who were pointed out as possibly affected as well as to some of the remaining relatives. Results Twenty-four probands fulfilled the criteria for CH or PCH; they had 142 first-degree relatives, of whom five were found to have CH or PCH, including one case of CH sine headache. The risk for first-degree relatives was observed to be increased by 35- to 46-fold. Conclusion Our results suggest a familial aggregation of cluster headache in the Portuguese population. .
Diversos artigos sugerem uma significativa agregação familiar da cefaleia em salvas (CH) embora nenhum tenha incluído indivíduos com provável cefaleia em salvas (PCH), segundo critérios da Classificação Internacional de Cefaleias (ICHD-II). Objetivo Encontrar casos de provável cefaleia em salvas e avaliar a agregação familiar da cefaleia em salvas incluindo também esses indivíduos. Método Foi aplicado um questionário por telefone a 36 doentes que frequentaram uma Consulta de Cefaleias com diagnóstico de cefaleia trigémino-autonómica. Todos os familiares de primeiro grau referidos como possivelmente afetados e alguns dos restantes foram entrevistados por telefone. Resultados Em 24 doentes foi diagnosticada CH ou PCH e estes tinham 142 familiares de primeiro grau, cinco dos quais foram diagnosticados como CH ou PCH, incluindo um caso de CH sem cefaleias. O risco para familiares de primeiro grau foi 35-46 vezes superior ao da população geral. Conclusão Nossos resultados sugerem a existência de uma agregação familiar da cefaleia em salvas na população portuguesa. .

The pathophysiology of primary headache iscomplex and it includes several interactionsthat regulate the nociceptive process. The trigeminal-vascular system is perhaps one of theprincipal structures that generate pain due tothe integration of several pathways both centraland peripheral. In addition to this, the trigeminalvascular system also plays a central role inthe autonomic and visual symptoms that affectindividuals with headache and in the centralsensitization process. In this article we brieflydiscuss the main structures that participate in thepathophysiology of primary headaches and theirinteractions in the different levels of the centralnervous system...
